For tube equipment. I own and love Conrad Johnson and they have been a great company for support on the premier 11a that I bought used a few years ago. The PV 11 preamp is close to ten years old and other than a tube swap, works Great!!!
Most reliable equipment manufacturers
I would like to know people's opinions as to which are the mist reliable manufacturers. In my book, reliability means: first and foremost, reliable and continued performance of the equipment over an extended period of time, but it also includes quality of workmanship, manuals/ease of use/design, shipping materials, upgradeability, customer service, choice of dealers, etc. For instance, in my experience I give Thiel an A rating, Sony a C.
